New long-term Zeposia (ozanimod) data demonstrate durable efficacy and consistent safety in relapsing forms of multiple sclerosis

These findings showed that patients receiving continuous Zeposia treatment for up to five years experienced low and stable rates of whole brain volume (WBV) loss through Month 60 (annualized least squares mean [LSM] % change from parent trial baseline: RADIANCE, 0.27; SUNBEAM, 0.35). Additionally, findings from a separate DAYBREAK OLE safety analysis demonstrated declining or stable incidence rates of treatment-emergent adverse events (TEAEs), with relatively low rates of infections, serious infections and opportunistic infections over more than eight years of treatment with Zeposia.

These data and 12 additional abstracts will be presented at the 40 th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Copenhagen, Denmark taking place September 18-20, 2024.

“If not treated early upon diagnosis, multiple sclerosis can lead to significant, irreversible brain volume loss and cognitive decline,” said Jeffrey Cohen, MD, Mellen Center for Multiple Sclerosis, Cleveland Clinic, Cleveland, Ohio and a paid consultant for Bristol Myers Squibb. “These new analyses reinforce the well-established safety and efficacy profile of Zeposia as an effective oral therapy, especially for newly diagnosed patients living with relapsing forms of multiple sclerosis.”

Reductions in brain volume loss with Zeposia treatment; The DAYBREAK OLE trial included 2,257 patients from the SUNBEAM and RADIANCE Phase III trials and evaluated rates of brain volume loss (Poster #P1623). Switching from interferon beta-1a (IFN-beta) to Zeposia treatment consistently reduced rates of WBV loss (annualized LSM% change from RADIANCE baseline to Month 24 and DAYBREAK baseline to Month 24: 0.48 and 0.19, respectively, with a similar pattern observed in SUNBEAM). Additionally, similar reductions were observed for change in thalamic volume loss. High annualized LSM% reductions in cortical grey matter volume (CGMV) were observed with IFN-beta (annualized change at Month 12 relative to SUNBEAM baseline: 1.02; annualized change at Month 24 relative to RADIANCE baseline: 0.59), but this trend reversed 12 months after switching to Zeposia in DAYBREAK (annualized LSM% increase relative to DAYBREAK baseline: patients from SUNBEAM, 0.10; patients from RADIANCE, 0.20), with low annualized LSM% CGMV loss observed thereafter.

Established Zeposia safety profile confirmed with more than eight years of DAYBREAK data: The final DAYBREAK OLE safety analysis (Poster #P1609) included 762 patients who were treated with continuous Zeposia with a median exposure of 83.9 months. Incident rates per 1,000 person-years decreased over time from the Phase III trials to Month 60 or more of the DAYBREAK OLE trial. Decreases were observed for overall TEAEs (896.1 versus 101.7), infections (300.5 versus 142.6), opportunistic infections (12.0 versus 4.9), cardiac (22.8 versus 9.5), hepatic (77.0 versus 15.7) and pulmonary disorders (11.3 versus 4.7), respectively.

“The data presented at ECTRIMS further reinforce the long-term safety and efficacy of Zeposia and add to the robust body of evidence demonstrating its potential impact on decreasing disease progression over time,” said Alyssa Johnsen, MD, PhD , senior vice president and head of clinical development, Immunology, Cardiovascular and Neuroscience, Bristol Myers Squibb. “Building on our expertise with Zeposia , we are expanding our pipeline as we continue to look for new ways to advance the field of neuroscience. New modalities and disease targets fuel our goal of delivering medicines that elevate standards of care across neurological diseases, including multiple sclerosis.”
